we plan to develop a webbased 3D GIS using PostGIS 2 and GeoServer with a W3DS. The architecture works fine, but i have problems to import 3D geometries into PostGIS. The geometries come from AutoCAD ...

I just followed the advice of this forum post in order to export the vector layers of a PDF for usage in ArcMap. The map vector layers in the PDF were spatially referenced. I was able to export the ...

I have loaded GPS points into a QGIS vector layer.
I also imported a vector line from a dxf file which doesn't have georeferencing.
I would like to fit in line geometry between the GPS points - how ...

I'm currently trying to import a 3D contour file into a Quantum GIS project. My question is, how can I export the DXF file from Microstation with height information? I already have imported it to the ...

I'm not very skilled on using postgis but I face a problem that I must solve, i.e. create tables to load geographical data stored as dxf.
I have a thousand dxf files (3d) with polylines, points and ...

I am trying to convert from dxf to shp. Any text layer when converted has attributes including text, height, and angle. The angle is in radians, and I can see that it is in degrees in the dxf file. ...

We have been using ogr2ogr to export data from PostGIS into DXF. Using the default behaviour of the export, all data are put into layer '0'. We would put data into a layer name from the PG table name. ...

I am using ArcView and ArcCatalog 9.2 with the Data Interoperability extension and I have 159 .dxf files that are comprised of 6 files; a dessin DAO, an annotation DAO, a multipatch DAO; a point DAO, ...

I'm using Python and OGR to extract the layers of a DXF file and convert them into SHP.
I began with:
import ogr, os, sys
driver = ogr.GetDriverByName('DXF')
datasource = driver.Open('test1.dxf', 0)
...

I am doing as constructed drawings which require the information to be in a GIS system and more specifically drainage as constructed drawings.
I must have a separate file for Pipes and Pits. First I ...

Does anyone know if it's possible to create a 3D dxf with OGR. I would like to assign our contour lines a z value and export them to dxf for some cad work.
PS I know FME can do this, however I would ...
